ROCHESTER — Anguish and uncertainty have marked the last 102 days for the parents of missing Rochester journalist James Foley, whose whereabouts is still unknown after he disappeared in Syria last year.

The Foley family renewed its public plea for help Monday, calling on those who might have kidnapped James Foley to contact them with news of their son’s condition.

“We have not heard from Jim for more than 100 days,” his father, John Foley, said Monday. “We want Jim to come safely home and we need to speak with him to know he’s OK. Jim is an objective journalist and we appeal for the release of Jim unharmed. Someone in Syria knows what happened to Jim and we hope they will contact us.”

On Nov. 22, 2012, unidentified gunmen kidnapped Foley, 39, near Taftanaz, in the Idib region of Syria near Turkey, according to information provided by the Foley family.

“We still have no idea who has him at all,” mother Diane Foley said Monday. “It’s very frustrating and upsetting, obviously.”

Foley, 39, has worked in a number of conflict zones around the Middle East, including Syria, Libya and Iraq.

While covering the hostilities in Libya, Foley and other journalists were taken captive by forces loyal to the government and later released. Most recently, Foley was contributing videos to Agence France-Press while in Syria.

“It’s just very difficult,” Diane Foley said. “We just thought the last time, in 2011, when he was detained in Libya, was difficult, but at that point, we knew who had him, and he was alive. This is so much worse.”
